Yup, a lot of us remember that. All the dungeons are nerfed into oblivion. I remember when ZF was buggy, and hard as fuck. You wanna summon Gahz'rilla? Nah son, you better have that hammer from hinterlands to hit that gong. Oh, you didn't go through 50 elites to get the hammer? Well you anit ever seeing that boss.
I remember doing that questline back in the day to get the hammer. Shit was bonkers.
Still have it on my Hunter in his bank.
It's rare that any pre-MoP dungeon will take more than 20~ min, and that'd likely be due to the dungeon being a long walk rather than hard.
Pretty much.
Basically, if you're having issues in a dungeon, it's typically due to one or two baddies just being bad.
